With a rigid, carbon-fiber tub in the best Ferrari tradition, the Alfa Romeo 4C’s trump card is a waiflike curb weight of roughly 2500 pounds. But there is much more to Alfa’s new mid-engine entry, like neck-snapping Brembo brakes, ultrasticky Pirelli PZero rubber, and unassisted and unfiltered steering. Power is courtesy of a 237-hp, 1742-cc turbocharged four-cylinder engine that tattoos your eardrums with lust and desire. The banzai Italian, limited to 3500 units a year, can even outsprint the much more expensive Porsche 911 Carrera to 62 mph.
